Update: 26/07 @ 10pm GMTThe status of the new
update has changed to In Review as of about three hours ago.

Update: 27/07 @ 4:45am GMTLooks like Apple didn't
consider the situation extenuating enough. To be fair to them, they've got their
own problems right now with the developer website hack. This meant the normal
expedited review form is off line, so maybe they didn't read the review notes
begging for the expedited review, and maybe the support email I sent wasn't able
to make it to the right department in time. Either way, at this stage I don't believe
there'll be an update this weekend. If you can,
please use these instructions to roll the update back. (Windows users: replace
the word "Finder" with "Windows Explorer",
and "Trash" with "Recycle Bin".)

Update: 31/07 @ sometime am GMTThe 2.0.1 update
has been released to the App Store. This release contains the fixes listed below
and should rectify the reliability issues from the 2.0.0 update. A couple of users
have updated and have confirmed they are finding LTP stable again. Now the work will
start to add back the double-tapping option, and a few other usability requests. The
website will be brought back on line shortly.

We stuffed up

There's no other way to describe it; there are no excuses to make. You
counted on LiveTrax Pro to not let you down, and it did in the worst
possible way.

In fact, we did.

At this stage, another update has been submitted to the App Store, and
we've begged Apple to expedite the approval process. However, there still
some time before we'll know whats happening.

After all the feedback, three serious bugs were found:

Large music libraries (in the thousands of songs plus range) cause LTP to take
too long to start, hitting the iPad's time limit for app startup. This would cause
the iPad to terminate LTP.

Scrolling the setlist to the extreme beginning and end, so that no songs were
showing, would cause LTP to crash.

Deleting a duplicate song added by accidentally double-tapping the track list
would cause LTP to crash.

All of these have been fixed. On top of that, the following usability bugs were
fixed:

Selecting a song in the setlist won't replace the currently playing song.

Selecting a song in the setlist always cues it when nothing is playing.

In some instances, you had to tap a song more than one time to cue it.

Sometimes, play had to be tapped more than once to start the cued track playing
